Ok, I had a closr look in Wikidata and it seems that the entry for Humboldtforum, which covers the actual museum and the museum building is more suitable (Q20196262). I change this now.

Yes, the original building (palace) doesn't exist anymore (it is of type Q19860854). The actual building is the reconstruction (housing the Humboldt Forum) with Wikidata-ID Q1636886 (OSM is not a place for abridged buildiings)

Hi Andrea,
sorry, we created accidently a duplicate wikidata entry for this building and assigned that to the osm outline. Now I merged the wikidata entries to Q109122153 and reasigned this id to osm.

Unter diesem Titel wurde das Gebäude ursprünglich errichtet und bekannt in der Fachliteratur. Wenn das Bauwerk inzwischen anders genannt wird, kannst du den Namen in Wikidata gerne als Alias ergänzen.

Er gehört als Teil mit zu dem umschließenden Gebäude (mit demselben Wikidata-Tag). Grundlage sind die Originalgrundrisse von Behnisch Architekten.

yes. the wikidata tags are inserted with a special transfer prog (connected to database archinform.net). This software only supports wikidata tags (right now).

Other question on studying the changesets: Why did you remove the wikidata and wikipedia tags (December 3, 2021 2:37 AM)?

That's strange! In the changeset there is indeed noticed, that I changed the url together with the wikidata tag, but I really don't know that I I have done this...

Hi janolezab, I only added the wikidata ID, didn't changed other tags...

You can add the tag to the schoolground, but please don't remove it from the buildings (or create a relation which include all buildings, etc from the school and tag this one only)

Thanks, good to know
